And you shall love the LORD your God with all your heart, and with all your soul, and with all your might.
All Commentaries on Deuteronomy 6:5 Go To Deuteronomy 6
Gregory of Nyssa
AD 394
If one does not love God with all his heart and with all his soul, how can he care wholesomely and guilelessly for the love of his brothers, since he is not fulfilling the love of the One on whose account he has a care for the love of his brothers? The person in this condition, who has not given his whole soul to God and has not participated in his love, the craftsman of evil finds disarmed and easily overpowers. .
